5. Kirsten Langer & Dustin Hebecker
Pro & Contra
24/7 energy production
No weather influences
Ecological
Sufficient space available
Lunar resources can be used to make:
Ceramics, glass, oxygen, concrete, solar cells & water
Lunar eclipses
Just on one side of the earth at one time
Global grid or energy storage necessary
Dangers of high energy beams

Vacuum tubes -> no air friction
18/09/18
Kirsten Langer & Dustin Hebecker

10. Vacuum Trains: History
Idea since 1910s by Goddard and Weinberg
Already realized in a non vacuum „low-speed“-version as Transrapid
First idea for Swissmetro in 1974 by Nieth, liquidation of Swissmetro AG in 2009
Patent for ETT by Oster in 1999
Patent for StarTram by Powell and Maise in 2001

21. Future Living The Venus Project, Seasteading
A concept by Jacque Fresco (designer and free thinker)
Use technology to change society and be environmental friendly
Use resource based and non monetary system
Motivation of work? Self realization?
Seasteading
Seasteading institute founded by Patri Friedman
Supported mainly by libertarians
Changing existing societies is difficult
Create new space outside of existing states (i.e. on the sea) to experiment with political systems
Success can inspire others
